IMPROVEMENT IN NEEDLE-SETTERS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 149,764, dated April14, 1874 application tiled October 18, 1873,

To all whom it may concern Be it known that I, HUGH H. V. LILLEY, ofMilford, in the county of Worcester and State of Massachusetts, haveinvented a new andvaluable Improvement in SewingMachine- Needle Setters;and I do hereby declare that the following is a full, clear, and exactdescrip-l tion of the construction and operation of the same, referencebeing had to the annexed drawings making a part of this speciiication,and

to the letters and figures of reference marked thereon.

Figure l of the drawings is a represen tation of a front view of myneedle-setter. Figs. 2, 3, 4f, and 5 are detail views of the same.

v This invention has relationv to `means for setting the needles ofsewing-machines; and it consists in the construction and novelarrangement of the spring-setter, as hereinafter more fully set forth.

In theaccoinpanying drawings, the letterA designates a needle-bar oftheHowe machine, to which my invention is represented as applied, althoughit may readily be attached to other machines in common use. B indicatesthe needle, the upper part a of whose shank is enlarged to securestrength and steadiness in the socket or holder of the needle-bar. Forengagement with the spring-setter, this enlarged portion ot' theneedle-shank is notched transversely at I), a little below the partwhich enters the socket of the needle-bar. C represents the set-screw,which serves to secure the needle in place when it is properly adjusted.D indicates the screw by means of which the spring-setter is secured tothe needle-bar. This is usually arranged on the face of the needle-bar,below the set-screw U. E represents the spring gage'or catch. This isformed ol' thin springsteel, the blank being firststanlped or cut in theshape indicated in Fig. 5 of the drawings, when a long arm, c, isconnected at right angles with a short arm, d, which is provided with aperforation, e, for the passage of vthe clamp-screw I). For the purposeof accurate adjustment of the setter, this perforation is made somewhatelongated vertically. The long or horizontal arm c of the setter isprovided with an extension, f,

which, before the device is tempered, is dea signed to be bent outward,to serve as a handle. It is also provided with two lugs or projections,one of which, lettered g, is located near the handle f, and extends fromthe upper edge of the arm c, which is doubled or reversely bent at h,between the arm d and the needle, inward or toward said needle. Theother projection, lettered 7c, is bent outward from the lower edge ofthe arm c, near its angular connection with the short vert-ical arm d.The object of the latter projection is to enable the operator to adjustthe setter in place, besides serving to give it strength and rigidity inthis portion. The object of the projection g is to engage with the notchb of the needle when the latter is pushed into the socket of theneedle-bar the required distance, thereby locating the needle, and atthe same time holding it up in the socket until the setscrew C istightened.

Then the needle is to be taken from the needle-bar the set-screw C isloosened, and the arm c, carrying the catch g, is retracted by means ofthe handle j', allowing the needle to drop, or to be easily withdrawnout of the socket.

Itl necessary, the setter may be rotated to either side out of the way,the clamp-screw l) being first loosened.

Ii the needlebar is rounded, a tlat seat, z, should be provided for theperforated vertical a-rm d of the setter.

What I claim as new, and desire to secure by Letters Patent, is-

The spri 11g-setter described, having the short arm d and the longhorizontal arm c reversel y bent at 7L, and provided with the lugs g k,bent, respectively, to the front and rear, and the handle-extension f,substantially as and for the purpose speciiied.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

HUGH HENRY VINCENT LILLEY.
